OILING DEVICE FOR INTERNAL-COMBUSTION MOTORS.

Application filed October 31, 1922. Serial No. 598,088.

To all whom it may concern:

Be it known that I, SAMUEL P. CUNNING- HAM, citizen of the United States, residing at Beaumont, in the county of Jefferson and State of Texas, have invented certain new and useful Improvements in Oiling Devices for Internal-Combustion Motors, of which the following is a specification.

This invention relates to new and useful improvements in an oiling device for internal combustion motors.

One object of the invention is to provide an oiling device designed for use on internal combustion motors and is specially adapted for use in motors similar to the type now used in Ford automobiles for the purpose of circulating lubricating oil from the rear end of the crank case through the valve rod chambers and delivering the same into the front end of the crank case.

Another object of the invention is to provide an oiling device through which oil may be supplied directly to the pistons and cylinder walls.

Another object of the invention is to provide an oiling device which may be used in connection with the circulating system now employed in the motors of Ford automobiles or which may be used to supplant the same.

A further feature is to provide means for supplying oil to the push rod chambers to keep the upper ends of the push rods submerged in oil to reduce the noise incident to the striking of said rods against the valve stems. I

l/Vith the above and other objects in View the invention has particular relation to certain novel features of construction, arrange ment of parts, and use, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 is a side view of a motor showing the oiling device applied thereto.

Figure 2 shows a side view of a tubular connecting nipple employed shown partly in section.

Figure 3 shows an enlarged fragmentary sectional View of the motor.

Figure 1 shows an enlarged bottom plan view of an oil chamber employed and,

Figure 5 shows an end View thereof partly in section.

In the drawings, the numeral 1 designates the motor having the crank case 2 formed with a circular housing 3 for the fly wheel. -The numeral l designates the cam shaft having the usual timing gear fixed on the front end thereof, said cam shaft actuating the push rods 6 through the cams 7, in the usual way to open the valves. On one side of the motor there is located the push rod chambers 8, 8 which are enclosed by the removable cover plates 9, 9. The push rods 6 work through the bearings 10 in the bottoms of the chambers 8 and are aligned with and actuate the valve stems 11 which work through the bearings 12, in the upper walls of said chambers 8. There is a tubular nipple 13 connecting the adjacent ends of the chambers 8. The upper side of the fly wheel housing 3 has a long transverse slot 1a and bolted on said" housing over said slot there is an oil chamber 15. Leading from the lower end of said chamber there is an oil line 16 which enters'the adjacent chamber 8 through the cover plate 9. The fly wheel runs in oil and splashes the same up around the housing 3 and said oil will pass through the slot M into the chamber 15 and flow by gravity into the adjacent chamber 8 and will fill the same with oil up to the level of the nipple 13 and the oil will run through said nipple into the other chamber 8 and will partially fill the last mentioned chamber with oil and will escape therefrom through the overflow port 17 into the front end of the crank case and will flow thence back through said case in the usual way thus keeping a continuous circulation of the lubricant. The oil line 16 with the connected chambers 8, one provided with the discharge port 17 form a continuous oil conduit leading from the chamber 15 of the fly wheel housing to the forward end of the crank case. The port 17 is located above the plane of the upper ends of the. push rods, so that said ends will be submerged in oil at all times and this will practically eliminate all noise incident to the striking of the push rods against the valve stems. If it is desired one or more ports 18 may be provided through the rear walls of the chamber 8 to permit the lubricant to enter the adjacent cylinders to lubricate the walls thereof.

The push rod 6 will thus work in oil which will greatly reduce the noise thereof and in addition thereto provision is'made for the free circulation of the lubricant throughout the motor.

What I claim is 1. The combination with a motor having a crank case formed with a fly wheel housing, of a lubricant chamber carried by said housing, said housing being provided with a port leading from the interior thereof into said chamber, a push rod chamber, and a lubricant conduit leading from said lubricant chamber and entering the forward end of the crank case, said conduit including said pushrod chamber.

2. The combination with a motor having a crank case formed with a fly wheel housing, of a push rod chamber, a lubricant con,- duit leading from the upper part of said housing and entering the front part of the crank case, said conduit including said push rod chamber. a b

3. The combination with a motor having a crank case formed with a fly wheel housing, said housing having a port in the upper part thereof, of an oil chamber carried by the housing and enclosing said port, a push rod chamber, a lubricant conduit leading from said oil chamber, and entering the front part of the crank case, said conduit including said. push rod'chamber, the cylinder wall ofthe motor having a port which communicates with said push rod chamber. '4. The combination with a motor having :a crank case formed with a flywheel housing and push'rod chambers, said housing having an oil port in its forward end, of an oil chamber carried. by said housing and enclosing the port thereof, a conduit leading from said oil chamber and discharging oil into one ofthe push rod chambers the other push rod chamber having a discharge port into thefront of the crank case, said push rod chambers being connected by an oil conduit.

5. The combinationwith' a motor having a crankcase formed with :a fly wheel housing andI-push rod chambers, said housing having an'oil port in its forward end, of an oil chamber carried by said housing and enclosing the port thereof, a conduit leading from said oil chamber and discharging oil into one of the push rod chambers, said last mentioned chambers being connected by an oil conduit, and the cylinder walls of the motor having ports leading from the push rod chambers.

6. An internal combustion motor having a crank case formed with a fly wheel housing, having an oil port through the upper part thereof, push rod chambers in the side of the crank case having ducts leading.

therefrom through the adjacent cylinder walls, one of said chambers also having an overflow port entering the front part of the crank case, said chambers being connected by an oil conduit in combination with a lubricant container enclosing said housing port and an oil conduit leading from said container and entering one of said push rod chambers.

7. The combination with a motor having a crank case formed with a push rod chamber having a side port leading through the wall of the adjacent cylinder, and an oil conduit leading from the oiling system of the motor and entering said chamber.

8. The combination with a motor having a crank case formed with a fly wheel housing a push rod chamber said chamber having an overflow port into the crank case, and an oil conduit leading from the fly wheel housing and entering said chamber.

9. The combinationwith a motor having a crank case formed with a fly wheel housing a push rod chamber said chamber hav ing an overflow port into the crank case, and an oil conduit leading from the fly wheel housing and entering said chamber, said chamber having a port through the adjacent cylinder wall, forming an oil duct into the interior of said cylinder.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses. H V
